SPECIFICATION forming part of Letters Patent No. 485,034, dated October 25, 1892.

Application filed December 29, 1891. Serial No. 416,484. (No model.)

T0 to whom it may concern:

Be it known that we, HARRY HANSON and JOHN EDWARD BERGMAN, both of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Elevator, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved elevator designed for use in excavations to raise or lower teams, material, &c., and which is simple, durable, and portable in construction and can be readily taken apart for storage or for transportation and set up in any desired place without the aid of skilled labor.

The invention consists of a frame, an elevator-cage held to slide in the said frame, and a bridge held adjustable on the said frame and projecting therefrom.

The invention also consists of certain parts and details and combination of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement. Fig. 2 is sectional plan view of the same on the line 2 2 of Figs. 1 and 3. Fig. 3 is a sectional side elevation of the same on the line 3 3 of Fig. 2. Fig. 4. is an enlarged perspective view of part of the frame and bridge, with parts removed and parts broken out. Fig. 5 is a perspective view of one of the bridge-irons for attaching the latter to the frame. Fig. 6 is a sectional plan view of one of the frame-posts and guideways for the bridge. Fig. 7 is a perspective View of one of the cross-beams for the frame. Fig. 8 is a transverse section of part of the frame on the line 8 8 of Fig. 3. Fig. 9 isa perspective View of one of the frame-posts, showing the notch for attaching a stay; and Fig. 10 is alike view of one end of one of the stays for the frame.

The improved elevator consists principally of three parts, the frame A, the cage B, fitted to slide in the said frame, and a bridge 0, supported on one end of the said frame and projecting therefrom to form an entrance or exit to or from the said frame at the time the elevator-cage B is in line with the said bridge, to permit teams to pass directly upon the elevator-cage over the said bridge or from the elevator-cage to the said bridge, as the case may be. The frame A, as well as the cage B and the bridge O, are so constructed that the several parts composing each of the three can be readily taken down for storage and transportation, and can be also readily put together in setting the device in any desired place.

As illustrated in the drawings, the frame A is provided with two bottom cross-pieces D and D, on which are doweledthe lower ends of the front and rear posts Eand E, respectively, the two front posts being connected with each other by a cross-beam E and a similar cross-beam being employed to connect the rear posts with each other at their upper ends. The corresponding front and rear posts are in turn connected with each other by longitudinal beams E and each longitudinal beam is braced by stay-rods E extending to the respective front and rear posts. The stay-rods E are formed with tongues fitting in correspondiugly-shaped grooves or recesses in the posts, as indicated in Figs. 9 and 10, so that the said stay-rods can be conveniently taken apart in knocking down the frame. In order to hold the front and rear posts together, bolts E are employed, connecting the two front or the two rear posts with each other at the cross-beams E as is plainly illustrated in Figs. 3 and 8.

It is understood that the several parts of the frame A mentioned are provided with dowels or tongues fitting into corresponding grooves, the said dowels and tongues being formed in any desired manner that is well known in joinery-work. The two cross-beams D and D are also connected with each other by longitudinal beams F, extending between the two corresponding front and rear posts, as is plainly illustrated in the drawings.

The cage B is provided with abottom frame G, made of two sides and ends joined together to be readily taken apart,the joint being made in any suitable manner. On this frame G are placed boards G to form a bottom for the cage, and on the said beams of the frame G is arranged a railing G the posts, top rail, and stays of which can be taken apart in knocking down the cage. In order to hold On theside beams of the frameGare se-- cured upwardly-extending ropes or cables H and H, passing over pulleys I and I, held in suitable frames bolted to the longitudinal-- beams 13 of the frame A. The front ropes or cables H, after passing over the pulleys I, ex-

tend downward and pass oversheaves "J; se cured on the inside of the front post-sE, about i. at their middle, as is plainly shown in Figs. 1' and 3. The ropes or cables H then extendrearward and passover pulleysK, held in a.

frame K ,'bolted or otherwise secured to the rear postsE. The frame K 'alsosupports double guide-pulleysK ,'between whichpasses the rope-H, so that the latter after leaving.

the frameA can be readily; passed upwardor downward or straightout'to connectwit'ha su1tab1e hoisting-machine orother means employed "for hoisting the cage. The rear'ropes or cables H, after passingiover thepulleys-I,

extend downward and pass over the pulleys.

K, alsoheld in the frame K above the pulleys' K; These ropes or cables H, after passing. under the pulleys K, pass between a double set of pulleys K ,'.whieh--permit the rope or cable to be extended upWardQdo-wnward, or straight out to connect with the hoisting-machine in a similar manner to the rope or'cable H; It is understood that the several ropes H andl-I are wound upon or unwound from the hoisting-machine at thesame time, so that an equal pull is exerted to raise or lower the cageB.

On the ends of the frame Got the cage B- and on the ends ofthetOprails of'the'railing;

G231? arranged pulleys L', engagingtracks or g'ui'deways N, securedon the inside of the postsE and E", so that the cageB can read Y travel up. and downon the frame Awhen the ropes or cables H and H are-pulled on or slack'enedup, as the case mayrequire.

The bridge 0 is'provided with a frame 0,-

having side beams and ends joined together tobe readily taken apart, and on this frame 0 are placed'boards P, forming a platform for the bridge. Railings Q are arrangedfon the sides of' the said bridge and are made of I posts and detachable top rails, the posts being. set into the side beams O and 'O of the frame 0.

In order to prevent sidewisedisplacementof the boards formingthe bottom for the brid e metallic stri s P are screwed or a a P bolted to the outside of the sidebeams O and I from sliding off the frame 0. The plates? further project at their inner ends beyond the b'ea'msO'- 0 as shown best in Fig.2, and

thus form stops for limiting the inward lateral movement of the said beams in their supportingsplates S "S and promote convenience in puttingthe'bridge together; The latter is also provided with a longitudinal middle beam 0 which, with the side beams O and O is joined at the outer end of'the bridge to the end O by' means-of dovetails,- as is plainly indicated in Fig. 2.

On the inner ends of the side beams O and O are'secured metallic keepers R, arranged in the shape of caps and formed at their front ,endswith dovetails R, engaging correspondiingl-y shaped dovetail grooves S" in metallic :pla-tes-S,boltedorotherwise secured on the outer sides of the front posts E of the frame ,-A. Each ofv the plates S is provided with a series of dovetail grooves S,so that the keeplers R maybe engaged with =lower or higherfgrooveaaceordingto the desired position of ithe bridge above the ground or excavation.

In order to strengthen the framethe side beams O and O are preferably' pro vided OIll "1ll18lI' under sides withsui-tablyiecon and g In making; excavations the frame Ans set up in the excavation and the bridge 0 adpass upon the said bridge and upon the-cage ';P and G are in the same horizontal plane.

lWhenthe team is on the cage, the latter can lbelowered by slacken-ing the ropes or cables- 1H and H 'until' the cage rests on" the cross- ;beams D of the main frame A. The-team can jthen drive-off the platform or floor-Gr into the Zexcavation or the wagon can be fllledwithexcavated material. When the wagon is filled with excavated material and again stands on the cage B, thelatter is hoisted by-pullingon the ropes-H and H until :it is in alignment with the bridge to permit theteam topass from the cage upon the bridge and from the latter upon the ground to cart off the'eXca' :Vated "material.
